I upgraded my Ubuntu set up to 12.10 and realized that the SD card can't mount like it used to every time I connected my Neo V (running android 2.3.4). It can't be a hardware issue as it mounts successfully via a card reader. It also mounts successfully on Windows 7 too.

For some strange reason the phone charges normally when the USB cable is connected but Ubuntu just doesn't recognize the connected phone or its SD card. How do I rectify this problem? Thanks in advance.
